Multiple React applications in one Spring Boot project

We have a Spring Boot based project where our frontend is written in React and try to build a single war file that has React build inside it. Now, we need to add one more React app into it. I tried to refer to this link, but not able to achieve the result. What changes should be done in order to add two React apps inside one Spring Project? The new react project name is er360, as per the suggested stackoverflow link, we need to consider the react app as a module. But after that it is mentioned that the React app needs to refer parent pom, something like this:
pom.xml (er360) (React app)
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>Mart-MCL-NewUI</artifactId>

This is my current

Milo OPC-UA Client NoSuchMethod error with io.netty.buffer.ByteBuf.writeMediumLE(int)

I downloaded the sample code from GitHub and modified the ReadNodeExample.java just to make sure that I can connect to an OPC Server (not Milo, it's a C#-based OPC Server). I was able to verify that the sample code is able to read/write/call nodes from my server with the modifications.
I then reimplemented what I thought I needed into my actual project, but I might be missing something since I cannot connect under this project and receive the following error:
java.lang.NoSuchMethodError: 'io.netty.buffer.ByteBuf io.netty.buffer.ByteBuf.writeMediumLE(int)'
This error happens in the ClientExampleRunner.run() while running createClient()
I can still run the sample project and still connects.
Here's my pom.xml:
The org.milo is added near the end and I added what I saw was added from the sample (included ch.qos.logback and jetbrains). Then added the io.netty thinking it would help, but still have the same error.

My modification to the KeyStoreLoader/ClientExampleRunner. I modified the name to match my application (even in the sample) but the most notable change is that I resolve the name of the machine dynamically
String hostName = InetAddress.getLocalHost().getHostName();
...
SelfSignedCertificateBuilder builder = new SelfSignedCertificateBuilder(keyPair)
.setCommonName("...")
.setOrganization("...")
.setOrganizationalUnit("eng")
.setLocalityName("...")
.setStateName("...")
.setCountryCode("...")
.setApplicationUri("urn:" + hostName + ":OpcServer")
.addDnsName("localhost")
.addIpAddress("127.0.0.1");
In the ClientExample, I only changed the EndpointUrl.

It seems that your actual project has an old version of Netty somewhere on its classpath.
ByteBuf::writeMediumLE (and all the other LE-suffixed ByteBuf methods) were introduced in Netty 4.1.

When you're new to Spring Boot then let Spring Initializr create your pom.xml. It will create a working pom.xml.

This is the error:
Error injecting constructor, java.lang.ExceptionInInitializerError: Cannot access defaults field of Properties
at org.apache.maven.plugin.war.WarMojo.(Unknown Source)
while locating org.apache.maven.plugin.war.WarMojo
I have tried:

https://www.programmersought.com/article/31114978502/
https://maven.apache.org/plugins/maven-war-plugin/dependency-info.html
Deleting the .m2 folder
"And" all the solutions on stackOverflow
I know this is not the best formulated question but i dont know what else to do...

I followed instructions in Comment by Piotr P. Karwasz. That worked out fine! The problem with one of the solutions i tried was the version number.
Solution:
https://maven.apache.org/plugins/maven-war-plugin/plugin-info.html

java.lang.NoSuchMethodError: org.glassfish.jersey.client.ClientRequest.getLengthLong()J

I am using arquillian to do integration tests against a Restful java API, these tests are executed using #RunAsClient annotation, the application is deployed on Wildfly 9.
The application tests were working but suddenly brake.
I am getting this error:
javax.ws.rs.ProcessingException: org.glassfish.jersey.client.ClientRequest.getLengthLong()J
that seems to be caused by this one:
Caused by: java.lang.NoSuchMethodError: org.glassfish.jersey.client.ClientRequest.getLengthLong()J
A piece of code:
#RunAsClient
#RunWith(Arquillian.class)
public class AuthTest extends AbstractBlackBoxIntegrationTest {
private static final String AUTH_URI = API_VERSION + "/auth";
#Test
#InSequence
public void testLoginAsValidUser(#ArquillianResource URL baseURI) {
WebTarget target = client.target(baseURI.toString()).path(AUTH_URI);
Response response = target.request(MediaType.APPLICATION_JSON)
.post(Entity.entity(getStudentRegularCredentials(), MediaType.APPLICATION_JSON));
assertOk(response);
response.close();
}
}

They've recently updated glassfish code and removed the ClientRequest.getLengthLong() and updated HttpUrlConnection code https://github.com/jersey/jersey/commit/4275389f727813aba883a7898f74948b8528018c.
If you update your
<dependency>
<groupId>org.glassfish.jersey.media</groupId>
<artifactId>jersey-media-json-jackson</artifactId>
<version>2.22</version>
</dependency>
to most recent version (or do <version>[2.22,3.0)</version>) that should fix all your issues.
